Environment day one project Global heat deaths are projected to increase by 370% if direct action is not taken to limit the effects of climate change. The dire implications of rising global temperatures extend across a spectrum of risks, from health crises exacerbated by heat stress, malnutrition, and disease, to economic disparities that disproportionately affect vulnerable communities in the U.S. and in low- and middle-income countries. In light of these challenges, it is imperative to prioritize a coordinated effort at both national and international levels to enhance resilience to extreme heat. This effort must focus on developing and implementing comprehensive strategies to ensure the vulnerable developing countries facing the worst and disproportionate effects of climate change have the proper capacity for adaptation, as wealthier, developed nations mitigate their contributions to climate change. To address these challenges, the U.S. Agency for International Development (USAID) should mobilize finance through environmental impact bonds focused on scaling extreme heat adaptation solutions. USAID should build upon the success of the SERVIR joint initiative and expand it to include a partnership with NIHHIS to co-develop decision support tools for extreme heat. Additionally, the Bureau for Resilience, Environment, and Food Security (REFS) within the USAID should take the lead in tracking and reporting on climate adaptation funding data. This effort will enhance transparency and ensure that adaptation and mitigation efforts are effectively prioritized. By addressing the urgent need for comprehensive adaptation strategies, we can mitigate the impacts of climate change, increase resilience through adaptation, and protect the most vulnerable communities from the increasing threats posed by extreme heat. Challenge Over the past 13 months, temperatures have hit record highs, with much of the world having just experienced their warmest June on record. Berkeley Earth predicts a 95% chance that 2024 will rank as the warmest year […]
